Vhile the coin controlled mechanism of the present invention is shown inthe accompanying drawings as embodied in a machine for vending papertowels it is to be understood as obvious that this inventionsubstantially asdisclosed or with suitable modification therein may beemployed for other purposes andmay be embodied in vending machines ofvarious types andkinds or in other forms of dispensing orservice-supplying devices. While the present invention is substantiallydierentiated from that disclosed and claimed in my prior copendingapplication Serial No. 39,442,1iled June 25, 1925, which became PatentNo. 1,723,948, August 6, 1929, some of the features of that inventionare retained in substantially similar form in the disclosed embodimentof the present invention, of which the magnet` feature is claimed in mycopending divisional application Serial No.- 133,615, filed September 4,1926, which became Patent No. 1,857,836, January 31, 1928, while thefeature by which the coin carrier is lockedin a position to close thecoin slot against the insertion of a coin when the magazine of thedelivery mechanism requires replenishing is substantially similar tothat claimed in my cepending Yapplication Serial No. 205,285, filed July13, 1927, which became Patent No. 1,728,901, September 17, 1929. Thedispensing features disclosed herein, as distinguished from and to theexclusion of the coin lcontrolled features claimed herein, are claimedas a di- "f visional part hereof in my copending application Serial No.273, 169, 1'iledApril27, 1928, for vWeb dispensing device, which becamePatent No. 1,738,721, December 10, 1929. An object of the presentinvention is to effect the extensive unidirectional rotation to apredetermined extent of a rotatable operating member the unidirectionalrotation of which is to be utilized for Vsupplying the desiredVservice.A Anotherobjectof the invention is to provide for the continuedunobstructed or uninterruptedl service-supplying rotation of thisoperating member by the successive feeding of coins to the'coincontrolled mechanism. prior. .to the completion of the U9 predeterminedextent ofrot'ation of this inem'- ber which is determined by theinsertion of each separate coin. Other objects of the invention are toprovide a coin controlled mechanism of this kind` which issimple,strong, durable, effective, compact, easy to manufacture, and which isparticularly adapted for heavy duty work. @ther objects and advantagesof the invention will herein- 1 after appear.

In accordance with the invention a pair of 60. continuously manuallyrotatablev driving members are positively connected or coupled togetherat all times for the unlimited concurrent .rotation of these connecteddriving members. One of these driving members during its continuedrotation causes to and fro movement lof a coin carrier while the drivingmember continues itsV rotation. Y/Vhen the coin carrier carries no coinit may be thus repeatedly operated idly while. the other or seconddriving member rotatesidly with the first driving member which operatesthe coin carrier. A continuously unidirectionally rotatable Voperatingmember the rotation of whichis to be utilized is normally idle anddisconnected from the rotatable driving members butmaybepositively'connected or clutched to the second driving member ltoberotated thereby.V A coin moved bythe coin carrier operates a couplingdevice by which' the rotatable operating member is coupled or l clutchedto the second driving'member and which automatically.disconnects the"oper ating member from the driving member when the operating member hasbeen rotated to the desired predetermined extent for rendering servicewhich is the equivalent of the coin. rlhis coupling device operates-onthe principle of a one-revolution clutch. However, the construction issuch that by supplying the returned "coin carrierV with anothercoin-before the operating member has completed a predetermined extent ofrotation theoperating member will remain clutched to the driving`member. and may continue its service- 95 supplying or dispensingrotation indefinitely by thus feeding successive coins to `the coincarrier. ,Y

VMore particularly, in carrying out the in- 100 vent-mute com carrier isrecited on aYPlVQt rra di while vthe two driving members and theoperating member are coaxial and have unitary rotation. The firstdriving member, which 'maybe a cam or the like, rocks the coin carrierand releases it to be returned by a spring, during'a `partei oneVrotation'of this driving member, while both driving members continueAtheir rotation and the o eratino memf ber being'limited, to'one completerotation resulting froinjtheinsertion of a single coin.

Therotatable operating member forms the in-Y itial driving or operatingmember for the dispensing or service-supplying device, which in thepresent instanceand as above noted vends paper towels, these towelsbeing contained in,

the machine'in the form of a continuous web, any desired uninterruptedlength of which may be obtained by successivelyinserting a correspondingplurality of coinsone after tions of parts as will appear from thefollow-V ing description.

At its top or upper end the coincarrierjis.

provfdedazwith; atransverseieir.heldigslot 81 to receive the lower edgeof a coin 82 inserted through a coin slot 83 in the upper front plate 9and with which the coin carrier slot 82 is normally in alignment, asindicated in dotted lines in Fig. 1. The upper portion of the coin isguidedby the right side of the frame lug 79 against which it may rest.The upper edge of the coin is received between and the coin ispositioned by the spaced poles of tie arms of a curved horseshoe magnet84 which is normally pressedagainst the stop lug 7 9 by a spring 85,this magnet being pivoted in a notched lug 86 on the frame plate 12 andloosely held in place by a screw 87. For discarding paramagnetic slugsthe magnet is rocked by a cam lug 88 on the coin carrier whichsuccessively engages a pair of small rollers 89 on the magnet.

The coin is moved by a finger 90 which engages substantially the centerof the coin and which projects from an inclined shoulder on the coincarrier, as shown, so that this finger is also effective to discardwashers. As the coin is moved by the coin carrier its upper edge engagesan adjacent lower tooth of a star wheel 91 and imparts one step ofrotative movement thereto. In carrying out the invention, this starwheel forms the primary operating element of a coupling device, as willhereinafter appear. The star wheel 91 is fixed upon the forward end of astar wheel shaft 92 which is journaled in a bearing on the upper part ofthe main frame plate 12.

As soon as the coin carrier starts its return movement the coin carriedthereby will drop upon the inclined floor 93 of la coin chute and slideinto the coin box 15 through its opening 17. This coin chute, which isformed on the main frame plate 12,'also has an upper or top wall 94 toassist in guiding the coins'through ythe opening 17V into the coin box.Disengagement ofthe coin from the returning coin carrier is assured andthe i' jamming of the coin againstl a tooth of the star wheel 91prevented by a kickoff pawl 95 pivotedon the frame 12 at 96 and lhavinga spring 97 which normallyurges it against a stop 98 with its free endin the path of the upper edge jportion of the coin; H

The coin carrieris returned toandnormally maintained at its normalretracted position by a retractilecoiled spring 99 anchored at one endto a lug on vthe frame plate 12 and at its other end connected to thelower part of the coin carrier through the intermediary of a flat bentlever 100 pivoted to the lower end of the coin carrier on a pivot pin101 and located in a deep slot in the coin carrier at theright. Theupper endv of this lever normally abuts against the bottom of this slotand forms a feeler for a coin inl the coin holding slot 81, across whichit may pass when this slot is empty but will be stopped by a cointherein. This result is brought about by a pairl of reversible pawls 102pivoted on the lower end of the lever. 100 which extends towards theleft, and urged by springs 103 to a middle position to wipe over andescape from the opposite ends of a saw-tooth ratchet 104 fixed on themain frame plate 12. A 4coin in the coin carrier slot 81prevents thereversal of these pawls on the ratchet 104 and thereby pre` vents thereturn of the coin carrier 76 from an intermediate position with theprobable consequent loss of the coins in the machine. The constructionof the coin carrier and the parts related thereto as so far describedare substantially similar to the disclosure in my above noted Patent No.41,723,948, with the exception that in carrying out the presentinvention the star wheel 91 has a dierent specific function.

Some lost motion is provided between the upper edge of the coin 82 andthe adjacent tooth of the star wheel 91 so that the coin will be movedout of alignment with the coin slot 83 in the upper front plate 9 beforethe coin begins to rotate the star wheel. vAs soon as the coin is movedout of alignment with this coin slot the coin carrier 7 6 will thenobstruct this slot againstthe insertion of another coin until the coincarrier has been returned to its normal position. Means are provided tomaintain the coin carrier 76 in a position to close the coin slot 83when the magazine becomes empty, thereby to prevent the loss of coins inthe machine.v .'For this purpose a locking lever is provided, shown asformed of a single bent rod having a hori-V zontal shaft portion 105pivoted in a bearing 106 on the main frame plate 12 adjacent itfs lowerright hand corner at the back` there-` o Y This shaft 105 at the left ofits bearing 106 has an upstanding locking arm 107 provided with aforwardly projecting locking end 108 to be projected through a hole 109(Fig. 3) in the frame plate 12 beyond the i forward face thereof andintothe path'lo'f. the lower right hand portion of the returning coincarrier 76, thereby to stop the return'movement of the coin carrierbefore it has uncovered the coin slot 83. Asprmg110.

engaging with the arm 107, urges the locking end 108 towards itsprojected position inthe return path of the coin carrier. At the otheror right end of the bearing 106 the "shaft 105 is provided' with adownwardly and rearwardly extending lever arm 111 Vwhich ter-Y minatesin a horizontal end portion 112 eX- tending towards the left in parallelrelationk This end vportion 112 carries a roller 113. J ust above themagazine f with the shaft 105.

at the rear of the roller 113which forms a feeler for the papertowelwelb 2,8.

The towelweb 28, just at the front of the front wall 21', holds theroller 113 out ofthe recess formed by the tongue 1141y and accordinglyholds the lockingk end 108 out of the return path of the coin carrier76, as shown in F ig. V2 and as indicated for the roller by brokenlinesin Fig. When the towel web 28 isl exhausted, as showninFig. 6, thelspring 110 will'swing the roller 113.into the recess formed by thetongue 114 and willi project the locking. end 108into the. return pathof the coin carrier 76.l The upstanding arm 107 which carries'thelocking end 108 is guided adjacent the latter yby a pair of lugs 115 onthe back of the frame plate 12. .The above described slot closing deviceis substantially the same as that disclosed andclaimed in m above notedPatent No. 1,728,901.

Manually operable means now to be described are provided in accordancewith the invention for rocking the coin' carrier 76 to and troregardless ot whether or not it carries a coin,-and when it carries acoin for then rotating the rotatable operating member or drive gear 7 5and for continuing its unidirectional operating. rotation after the coincarrier has been returned by its spring 99 t0 its normal'retractedposition.

According. to the invention, a pair ot continuously'rotatable drivingmembers are provided whichare positively connected 0r coupled togetherfor normal unlimited concurrent unidirectional rotation. One of thesedriving members is at all times normallyfei'- ective to rock the coincarrier 6 successively as this driving member continues its rotation,while the other or second driving member, which isfor rotating theoperating member or drive gear 75, isnormally ineffec- 'tive and mayrotate idly and to which the rotatable operating member 7 5 may bepositively connected:orcoupled to he rotated thereby by means of aclutching or coupling device op- Vera'ted by-a coin moved bythecoincarrier, 7 8.

This coupling ldevice' is so constructedthat after a predeterminedextent of rotation of the operating member the latterwill beautomatically disconnected from its driving member but so that suchdriving connection will -be maintained should another :coin besuppliedfto the returned coin carrier '.76k in theV meantime, whereby astrip of ythe paper towel web 28 ofr any desired length Vmay be thusobtained.

Instead olf thecam 118l and itstollower 117, it should beevidentth-atsome other Y device -having a similar manner of operationvv A mightV beemployed y:tor rocking the coin carrier 76.

In fact,theV cam armk 118 may be consideredgas forming-in effect a one-toothpinionl and the follower stud 116'v togetherv with its roller 11i' asforming a one-toothV rack, since the manneryof operationr` isas'ub.

stantially the same. y Y y In the embodiment of theinvention shown, thedrlvingmember for the operating-inem'- ber 75..is coaxial with thedriving arm 118 leo and is shown as a disc 122 spaced rearwardlysomewhat beyond the back of the frameplate 12 and provided at its frontwitha hub sleeve 123 journaled in a bearing extending through the mainframe plate 12 and at its rear this dise is provided with a hub boss124. At its forward end the hub sleeve 123 vis provided with asquare-shouldered diametral rib which seats in a correspondingcomplementary diametral groove in the rear end of the hub sleeve 119 ofthe cam 118, las shown in dotted lines in Fig. 4,'so that thereby thedriving disc 122 is positively connected to the driving cam 118 forunitary rotation therewith.

The driving head120 of the cam 118 is shaped to form the cup element ofa friction driving clutch of the cone type and having a cooperating coneelement 125. A rotatable handle knob 126 has a reduced hub portionjournaled in the reduced outer end of the bore in the front boss 121 andis positively Connected to the cone element 125 to rotate the latter bymeans of a square-faced diametral groove in the handle kn-ob hub inwhich is seated a complementary squareshouldered diametral ridge on theadjacent outer face of the clutch cone 125, as is shown in dotted linesin Fig. 4. A handle shaft 127 extends inwardly through the handle knob126,.cone clutch element 125 and loosely through driving cam 118 andVdriving disc 122. This shaft has a head 128 fixed on its forward end andfitting loosely in a bore or Vrecess 129 in the front of the handle knob126. As it is desirable that thehandle shaft 127 shall rotate with thehandle knob 126, the head 128 is provided with small wings to engage andslide in longitudinal grooves in the handle knob 126 at the outer end ofits bore 129 (Figs. 1 and 4). A coiled compression spring 130 on thehandle shaft 127 is interposed between its head 128 and thev bottom ofthe enlarged bore 129 in the handle knob. This spring is adjustablymaintained under suitable tension by a nut 131 on the inner end of thehandle shaft 127 engaging a washer 132 which abuts againstthe inner endof the hub boss 124Vv on the driving disc 122. Y

The spring 130 thus maintains the clutch elements 120 and 125 "infrictional driving engagement. The cone clutch element 125 will slip onthe cup clutch head 120 to prevent breaking any part of the mechanism,which otherwise might occur in an attempt to rotate the handle knob 126backwardly, in which case the back of the cam arm 118 will strikeagainst the cam roller 117 of the returned coin carrier 76. Also, whenthe coin carrier 76 is stopped andlocked against full return movementbythe lockingend 108 of the locking arm 107 the coincarrier then alsolis locked againstits normal free forward movementby reason of the factthat in the particular construction shown the coin carrier pawls 102will not reverse on the ratchet 104 to permit forward movement of thecoin carrier from its partially returned position, and in this case thecam roller 117 would limit the rotating movement of the cam 118 in bothdirections. This friction driving clutch connection just described issubstantially the same as that disclosed in my above noted Patent No.1,723,948, but is more compact by reason of the housing of the clutchspring 130 within the handle knob 126.

In the embodiment of the invention shown, the normally idle rotatableoperating member 75 is coaxial with and is directly mounted upon itsdriving member 122, which nor.- mally may be rotated freely to anunlimited extent independently of the rotatable operating member 75 withthe latter locked against operating rotation (see more particularlyFigs. 3 to 6 inclusive). rlhe operating mem# ber or drive gear 75 iscircularly recessed at the back to fit around the driving disc 122 andis apertured at the `front to fit around the disc sleeve 123 in thespace between this disc and the bearing-for its sleeve on the frame wall12. IThis operating member 75 is further supported upon the drive member122 by means of aback plate or cover plate 133, recessed or countersunkinto the back thereof and fitting around the disc hub boss 124 whichextends through it. This plate 133 is'lirmly secured to the :Operatingmember 75, such as by means of a pair of screw pins 134 and 135. Y n fThe circular 'driving disc 122, is peripherally notched to provide anabrupt driving shoulder 136 which faces in a clockwise direction and isshown as radial and as located at about O in advance ofthe radialdriving face of the coin carrier cam or driving mem# ber v118, aswill beevident by acomparison vof Figs. 3 and 5` and which also is shown ineach of Figs. 7to 10 inclusive; A normally disengaged 'coupling pawl137, shown'A as of substantially luneshape, tohave in'part a'cylindrical surface'and in part a concave arcuate surface complementaryto the circular periphery of the drive disc 122 and disposed immediatelyadjacent thereto, tob'e rocked into its `peripheral notch so asvto beengaged Y by its driving shoulder 136, passes through t-he operatingmemberl 75 in a ratherdeep arcuate notch in the wall of the circularre'- cess therein which "contains the driving'member 122. In the normal,or idle position of the operating member 75thepivotal axisV of izo.

this pawl 137 is above the axis of rotation of the driving disc 122substantially in vertical alignment therewith, and the left edge Y orpoint of thisl pawlwhich is to beengaged by the driving shoulder 136 iscircumferentially spaced in a' clockwise direction therefrom toaconsiderable extent to provide .lost motion, as shown ,in Fig. 5,butwhich appears. as somewhat less inFig. by reason of the fact that asthere shownthe driving disc. 122 has just begun its forwardrotation.

This coupling pawl 137 is providedat the rearl endthereof with anaXia-lstem or 'shaft portion 138 whichis pivoted in the back plate 133 oftheoperating member 75 and projects rearwardly beyond vthis plate. Theprojecting end portion of this stem 138 carries a coiled torsion spring139 one end of which is seated in adiametral slotin the stem and theother end ofwhich is extended and anchored to the operating member 7 5.by the plate screw 135 (Figs. 4, 6, 11 and 12). As

i is perhaps most clearly shown in Fig. .12, this spring constantlyurgesthe coupling pawl 137to rock towards vits engaging position, whichis clockwise as viewed from the rear in Figs. 11v and 12 andcounter-clockwise. as seen from tliefront in Figs. 5. and 7'to 10inclusive.

At its forward end VVthe coupling pawl 137 isi-provided coaxiallytherewith with a fiat circular'head140rwhich is countersunk into thefront face offthe Operatingmember down to thefforward face of thedriving disc V122, a portion of the operating member 75 pawl (Figs. 4,5V'and Because of its general 'shape and its manner n ofvoperation, thiscoupling'pawl- 137, con- Y l 'sidered as a whole, may be termed a drivelinger. This `organization lof the gear-form ing operating. member 7 5,with its driving member 122 and'itsclutch pawl 137 both substantiallyhousedtherei'n, provides a Vvery compact construction. "At its rear thisoperating member or drive gear 75fmay be provided withy a wideprojecting 'iiange (not shown) which forms aguide for theV towel fwebl28 tov prevent the possibility ofthis web catch- V-ingfupon orbeing-torniby the adjacent-end Y ofthe handle shaft 127 orV that of thepawl stem 138.*

v. The coupling pawlVV or clntch pawl :137 is normally heldV lat itsdisengaged position against the tension of its engaging spring 139'by'.means of a movable abutment, forming atri i latch for thepawlywhich is shown f as a at lever arm 142 eXtendingat adownwardinclination towards thefleft and the freefend of which form'sanabutment for the V.pawl studf141.A This lever'arm 142 forms oneofthearms of fathreefarmed latch lever whichisiiked upon the 4rearYendlof a pivot shaft. 143 which is journaled, as shown, in a bearing onthemain'frame plate 12A towards the right and upper part thereofandthrougli which the pivot shaft extends. Below its radialpawl-operating arm 142 this:V threearmed lever has another orsecondradial arm 144 provided with a right angular rearwardly turned end. 145which normally en- 1 gages beneath and in the path of forward movementof a stop lug 146 which projects from the forwardV face of thegear-forming operating member 7 5 lnear its toothed periphery` and whichis normally positioned attheA right of and somewhat below its axis(Figs. 5, 6 and 7). Thus the stop lug'146 in en` gagement with the stopend 145 ofthe lever arm 144normally positively locks the opel1` atingmember 75 against forward rotation.

The third arm` of this latch lever is an upstanding operating arm 147which is'bent or offset forwardly above the frame plate 12 so asv-tobring it just at the rear of the teeth of the star wheel 91 at therightA hand thereof.Y Thelever arm 147 is provided with a cam stud 148having thereon a camroller 149 which is normally seated'betweentwo oftheteethy of the star wheel 91 and among its other functions serves toposition the latter. The roller 149 is urged against the stary wheel 91by means of 'a coiledv retractile-'return spring 150 for'the three-armedlever asa whole, connected to the upper endof the upstanding arm 147 andanchored to the top of the main frame plate 12-(Fig.3)'. It will benoted that the teeth of the starwheel 91, which are equidistantlyspaced' and-shown as eight in number, have abrupt substantially radialdriving facesto be engaged the moving coin while the opposite faces ofthese teeth are inclined-to form cams forrockingV the lever arm 147against the tension of its' `return spring 150.

NormallyVV or when the coin carrier 7 car` ries no coin, upon forward orclockwise rota-L tion ofthe handle knob 126'the coin carrier or cam 118while' thev driving disc`122rwill 137, this idle movement ofthecoin-carrier,i however, being utilized for discarding' slugs ofyvariouskinds, some of'which"v have been mentioned. Then and as shown in F igs.l3 and 7 to 10 inclusive, the coin carrier 76"car ries a coin 82,.theinitial movement ofthe coin carrier willffirst move this coin beyond thecoin slot 83 in the lower frontlplate 10 and into contact with ythe4adjacent?lower tooth of the star wheeli91, the driving' shoulder 136 ofthe driving disc 122 also being correspondingly moved 'to a slightextent/toi wards the still disengaged couplingpawl1'37, this being thephase-of operation thatis shown in Fig. 7l l The moving coin'82 nowro'tate'sfth'e star 110 76 will be rocked idly by its kdriving member ili) wheel 91 which rocks the three-armed latch lever in a clockwisedirection, the movement of its upper arm 147 towards the right resultingin the inward movement of its lower arm 144 and in the raising of itsintermediate arm 142. This upward movement of the lever arm 142 liftsits abutment-forming end above the pawl stud 141 and disengages thelatter while at the same time the inward movement of the lower arm 144moves its locking end 145 free from and out of the path of the stop lug146 so that the operating member 75 is now set free to be rotated. Assoon as the lever arm 142 has released the pawl pin 141 the pawl spring139 becomes effective to rock the engaging end or shoulder of-the pawl137 into the path of the advancing driving shoulder 136 of the rotatingdriving disc 122, this shoulder now having moved forward closelyadjacent to the pawl. The phase of operation just described is shown inFig. 8, in which the clutch pawl or coupling pawl 137 has been set freeand is at its engaging position just at the front of the drivingshoulder 136 but with the rotatable operating member 75 still in itsoriginal or normal position, its rotation not having yet begun.

When the locking end or stop end 145 of the lower arm 144 has moved outof the path of forward rotative movement of the stop lug 146 on theoperating member 75, this stop end 145 has moved into the path ofrotation of a stop shoulder 151 formed on 'the forward face of therotatable operating member 75. During any time that the locking end 145is disengaged from the stop lug 146 the stop shoulder 151 will strikeagainst this lever end 145 and will prevent any more than very limitedrotation of the operating member 75 ahead of or independently of therotation of its driving member 122. The purpose of this is to preventthe unlimited pulling out of the towel web 28 during this stage of theoperation, and in the construction shown only a useless inch or so ofthe towel could be thus obtained. The normal space or lost motion shownas provided between its stop shoulder 151 and the locking end 145provides for the movement of the latter into and out of the path of thislug 151 in a normal operation.

In the intermediate stage of the operation shown in Fig. 9, theoperating member 75, coupled to its driving member 122, is being drivenforward thereby while the coin car rier 76 is still moving forward andthe lever arms 142, 144 and 147 on the three-armed latch lever have beenrocked to the fullest extent by the rotating star wheel 91, in which theroller 149 is riding over the end of a tooth of the star wheel.

Fig. 10 shows a succeeding stage of the operation in which a star wheeltooth has passed beyondthe roller 149 and the spring 15G has becomeeffective to seat this roller between the teeth of the star wheel and toreturn the lever arms 142 and 144 to their normal position with theabutment-forming end of the former in the path of the pawl stud 141 andwith the locking end 145 of the latter in the path of rotation of thestop lug 146.

The stop end 145 of the locking arm 144 has now moved out of the path ofthe stop shoulder 151 on the rotatable operating 1nem.

ber 7 5 which, being clutched to its driving member 122, is rotating asa unit therewith and with the coin carrier cam 118. The coin carrier 76has substantially reached the limit of its forward movement with its camroller 117 just ready to escape from the end of the cam arm 118, whichit will do at substantially the same time or immediately following thespring-returned movement of the star wheel roller 149, although this issubstantially immaterial. When Ythe cam roller 117 is released by thedriving cam 118 the coin carrier 76 will be immediately returned to itsnormal position shown in Fig. 3 while the cam 118, the driving disc 122and the gear-forming operating member 75 continue their rotation.

.As the operating member 75 approaches the end of a single completeoperating rotation, thepawl stud 141 will abut against the end of thereturned pawl-controlling lever arm 142 and as the pawl 137 is carriedforward by the driving shoulder 136 it will then rotate on its pivotalaxis until it is rocked out of engagement with the driving shoulder 136,whereupon the driving member 122 may continue its rotation idly whilethe operating member 75 will be positively locked against furtherrotation by its stop lug 146 coming into engagement with the stop end145 of the locking arm 144. It will now be understood that the abovedescribed coin-operated Coupling device operates on the principle of andin fact constitutes one form of a one-revolution clutch.

It will be noted that at the end of a full rotation of the drivingmember 75, when its drive pawl 137 has been disengagedy as above noted,thereturned coin carrier 76, which has discharged its coin, will havebeen moved by its cam118 away from its normal position and substantiallyto the position thereof shown in Fig. 8. Thus if the handle knob 126should then be immediately released while the cam roller 117 is still inengagement with the cam arm 118, the coin carrier spring 99 4inreturning the coin carrier will be effective to rotate the driving disc122 reversely to' 122 may be left in their idle rotative movement. It isnot deemed practicable to depend upon the paWl pin 141 `to stop therotation of the operating member 75 and hence the stop lug 146 andlocking lever end A5 are provided Yto form a. strong and positive stopand lock for the operating member.

During the unitary rotation of the coin carrier cam 118,5the drivingdisc 122 and the operating member 75 driven thereby, a second coin maybe inserted through the slot 83 into the coin holding slot 8l of thereturned coin carrier 7 6, in Which case the abutmentforming end of thepaWl-controlling lever arm l-iQ Will be lifted out of the path ofrotation or" the pavvl stud 14:1 in advance, as the coin carrier movesthe coin forward;

. thereby rotating the star Wheel 91, as Will be clear by an inspectionof Figs. 7 and 8. Thus any number of coins may be successively'insertedso that the operating member 7 5 may be rotated continuously for therebyobtaining a strip of the paper towel Web 28 oi any length desired.

It is lobvious that various modifications may be made in theconstruction shown in the drawings and above particularly described,Within the principle and scope of the invention as deiined in theappended claims.
